Propranolol in hypertension.

Methods Twenty-five hypertensive male patients aged between 47 and 67 years (mean 54.6) attending the long term anticoagulant and hypertensive clinic at the County and Clayton Hospital in Wakefield were included in the trial. One patient withdrew because of side-effects. Eleven patients (Group 1) suffered from angina of effort, with or without myocardial infarction and were receiving glyceryl trinitrate tablets for attacks of angina. None of these patients had received any anti-hypertensive therapy previously. Three of them (Nos. 1, 5 and 6) had suffered from ventricular tachycardia following myocardial infarction and were taking maintenance doses of quinidine sulphate, 200 mg 8 hourly, to prevent arrhythmia.
